Social Network Service (SNS) 지속사용에 관한 연구: 사용자의 SNS 리터러시 조절효과를 중심으로 = A Study on Continued Use of Social Network Services: Focused on the Moderating Effect of User`s SNS Literacy

다국어 초록 (Multilingual Abstract)

The development and expansion of communication technology in the field of information technology (IT) have changed the method and culture of communication, mediating communication among people. In particular, since social network service (SNS) has the attributes of information delivery and processing, it has a more powerful dissipating effect and influence than other existing communication methods. The role of users in SNS is important because it has the communication structure of producer-consumer, which consists of sharing, connection and participation of users. In this line, the purpose of this study is to investigate the intention for continued use of SNS by user ability. In order to explain the motivation and behavior for continued use of SNS by users, this study employed the motivation theory and post-adaptation model. The study applied ``media literacy`` to the characteristics of SNS media and environment and expanded it into the concept of ``SNS literacy`` to identify the moderating effect by user ability. Referred to as ``user`s ability that is required to use SNS,`` the SNS literacy was verified for its moderating effect with the three sub-dimensions: ``technical accessing ability,`` ``understanding ability`` and ``creative ability. ``The major findings of this study are as follows. First, the perceived usefulness and playfulness were found to have a significant effect on the intention for continued use of SNS, showing the same result with previous studies on technology acceptance. In other words, usefulness and playfulness are variables with an explanatory power in the SNS environment as well. Second, the conceptualization of SNS literacy with accessing ability, understanding ability and creative ability was found to be valid. Third, it was verified that there was a significant difference in the SNS literacy between perceived usefulness and continued use, indicating that users with higher ability respond sensitively to usefulness and affect continued behavior. The moderating effect of SNS literacy was also verified in the relationship between perceived playfulness and intention for continued use. The results above confirm the difference in post-adaptation behavior of individuals, and are expected to provide several implications.
